How to Convert Megateslas to Femtoteslas
The megatesla and femtotesla are both units of magnetic field. By definition, 1 megatesla equals exactly 1e21 femtoteslas. This means to convert megateslas to femtoteslas, you multiply by 1e21.
Formula
Step-by-Step Example
Convert 5 MT to femtoteslas:
We need to convert megateslas to femtoteslas
Since 1 MT = 1e21 fT, multiply by 1e21
5 × 1e21 = 5e21
5 MT = 5e21 fT

About These Units
Megatesla (MT)
A megatesla (MT) equals 10⁶ teslas. Found only in astrophysical objects: neutron star surfaces 10⁸-10¹¹ T, magnetars up to 10¹¹ T. The strongest magnetic fields in the universe. Impossible to create on Earth.
Femtotesla (fT)
A femtotesla (fT) equals 10⁻¹⁵ teslas. Measures biomagnetic fields: human brain activity 10-1000 fT, human heart (MCG) 1-100 pT. SQUID sensors can detect sub-femtotesla fields. At the frontier of magnetic field measurement.
